Ubiquiti UNAS-2-W UniFi Storage with (2) 3.5" HDD bays, WH

Ubiquiti UNAS-2-W UniFi NAS Storage

Overview

The Ubiquiti UNAS-2-W is a compact network-attached storage device designed for UniFi ecosystem deployments. This two-bay NAS integrates directly into UniFi Network management, providing centralized storage for surveillance footage, backups, and network data without requiring separate NAS infrastructure. The UNAS-2-W (model number included) ships with a PoE++ power adapter, eliminating the need for dedicated power outlets in many deployment scenarios while maintaining a small footprint suitable for wall or desktop mounting.

Key Features

The device accommodates two 3.5-inch HDD bays, supporting substantial storage capacity for multi-camera systems or enterprise backup workflows. Network connectivity is handled through a single 2.5 GbE port, providing sufficient bandwidth for concurrent camera streams and data transfer operations without requiring additional network infrastructure upgrades. Management occurs entirely through the UniFi Network application, allowing administrators to configure storage policies, monitor capacity, and retrieve recordings from a unified interface alongside network and security devices.

Deployment Scenarios

The UNAS-2-W serves distributed storage needs in small-to-medium UniFi installations, branch offices, and remote sites where on-premise recording is required. Its compact form factor makes it suitable for wall mounting in network closets or equipment rooms. The device is particularly effective as local storage for UniFi Protect camera systems, enabling redundancy and reducing reliance on cloud storage for archived footage.

Network Integration

The 2.5 GbE connection integrates seamlessly into existing UniFi Switch infrastructure, particularly alongside PoE++ switches that can power compatible devices. Because the Ubiquiti UNAS-2-W operates within the UniFi ecosystem, configuration and monitoring require no third-party NAS software—everything functions through native UniFi Network controls.

Installation Notes

The unit weighs 2.850 lb and supports both vertical and horizontal mounting. The included PoE++ adapter enables flexible placement independent of nearby power availability. Hard drives are installed from the front panel without requiring case disassembly, simplifying maintenance and drive replacement. The white finish integrates into standard office environments.

Eden Phillips, Infrastructure Specialist

"The UNAS-2-W fills a specific role in UniFi-native deployments where administrators want to avoid managing separate storage systems. The two-bay design and 2.5 GbE port provide adequate throughput for most small commercial camera systems. Key consideration: verify your switch supports PoE++ delivery before depending on the included adapter for power. Direct gigabit+ switching ensures you're not bottlenecking recording or retrieval performance. The Ubiquiti UNAS-2-W works best when you're already committed to UniFi management—if you need multi-protocol NAS features or cross-ecosystem compatibility, traditional NAS appliances remain more flexible."
